METAL DOOR.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed July 10, 1914. Serial No. 850,222.

The invention relates to an improvement in metal doors, and particularlyto a door cast in two sections.

In the present invention, the improved door is constructed with a viewto providing a cast structure made. up of two sections, whereinprovision is made for the locks, hinges, and for properly bracing thesections when they are assembled in door forming relation.

The invention in the preferred form of details will be described in thefollowing specification, reference being had particularly to theaccompanying drawings, in which:

Figure 1 is a view in elevation, partly broken out of the improved door.Fig. 2 is an enlarged broken section on the line of Fig. 1. Fig. 3 is anenlarged broken elevation, showing one corner of the door structure.Fig. 4 is a section on the line 44' of Fig. 3. Fig. 5 is an enlargedelevation, showing the lower corner of the door structure. Fig. 6 is anelevation partly broken out ofa portion of the door structure, showingthe lock housing. Fig. 7 is a section on line 77 of Fig. 6. Fig. 8 is abroken sectional View through the door structure.

In constructing the improved door, the respective sections are made upas castings, though it is to be understood that there is no limitationintended herein .as confining the invention to a cast door.

The door proper is constructed of two sections 1 and 2, each formingapproximately one-half of the door structure, divided centrally andlongitudinally, so that one section includes the outer face of the doorand the other section the inner face. The section 1, which will betermed the main section, is formed to provide ofisets 3 forming thelower rail of the door, side offsets 4. forming the stiles, anintermediate ofi'set 5 forming the central rail of the door and theupper offset 6 forming the upper rail of the door. The spaceintermediate the lower and center rails and the stiles is in theparticularly shown type of door illustrated formed to provide anintegral panel 7 the material of the panel being in the center line ofthe door. The space between the center and upper rails and the stiles isin the particular type of door shown free of connection to provide forthe reception of the removable panel 8, such as glass or the like, theconstruction for securing-which will later appear. The edges of the doorforming the margin of the section 1 are turned inwardly to provideone-half the thickness of the door forming the side and end edges 'as at9.

The section 2 is practically a duplicate of the section 1 having theoffsets to form the hanging and lock stiles. and the upper section andlower rails. In this instance, the panel strip 7 is omitted, the panelstrip of the section 1 serving as the panel formation. Furthermore, theinner marginal edge of the section 2 for the upper and center rails andthe side stiles is formed to provide a slight extension beyond thesimilar edge of the section 1, whereby to form a projecting shoulder orledge 10, against which the panel 8 rests when in position, as willlater appear.

The hollow sections forming the rail and stile offsets are in theircasting formed with transverse and longitudinally extending ribs 11,coextensive in height with the similar dimension of the offset, andsimilarly arranged in each door section, as clearly shown in Fig. 4.These ribs abut squarely when the sections are assembled andatappropriatepoints throughout the ofi'sets each section is formed thereinwith enlargements 12 in the form of bosses each of which is formed with.

a suitable opening '13, so that when the sections are assembled, rivets14 or other securing means may be readily applied. The outer wall of thehanging stile offset is thickened at appropriate points as at 15 toprovide for securing hinges 16 thereto, as shown in Figs. 3, 4, and 5.At an appropriate point in the lock stile, the offsets of the respectivesections are formed with spaced parallel ribs 17 formed when thesections are assembled to provide a mortise 18 to receive the lock 19.

With the door sections assembled, the upper panel 8 is placed inposition resting against the shoulders or ledges 10, and the angle plate20 is secured against the opposed side of the panel resting upon themarginal edge of the side and stiles and upper and lower rail of thesection 1, being secured in place by screw bolts 21. i

The improved'door is constructed in two sections, and these two sectionsare so formed as to present practically complete a metal door in whichnecessary reinforcement is properly provided for and provision made forsecuring all necessary attachment.

\Vhat is claimed is '1. A metal door made in two sections, eachincluding one face of the door, each section being formed with offsetsto provide a portion of the respective rails and a portion of thestiles, the interior of each offset being formed with integralstrengthening ribs and with riveting bosses, the ribs and bosses of therespective sections being coextensive in height with the depth of theolf- Sets and abutting when the sections are assembled.

2. A metal door made in each includin one face of the door, each sectionbeing 'ormed with offsets to provide a portion of the respective railsand a portion of the stiles, cooperating stile effects of two sections,

each section being formed with spaced par allel ribs to abut when thesections are assembled for forming alock mortise.

3. A metal door formed in two sections each including one face of thedoor, each section being formed with oil'sets to provide upper, centerand-lower rails and stiles, one section in the space between the stiles,lower and center rail having an integral plate to form a panel, thespace of one section between the stiles, upper and central rails beingopen and presenting a marginal edge at right angles to the face of therespective sections, the edge of the other section corre-- sponding tosuch open portion of the first mentioned section being extended inwardlybeyond said marginal edge to form a ledge.

4. A metal door formed in'two sections each including one face of thedoor, each section being formed with offsets to provid upper, center andlower rails and stiles, one

' spending to such open portion of the first mentioned section beingextended inwardly beyond said marginal edge to form a ledge, and aremovable panel bearing on said ledge, and means engaging such marginaledge for securing the panel in vplace.

In testimonv whereof I atlix my signature in presence of two witnesses.
